This invention relates to rail joints, the object in. view being toprovide a reinforced rail joint which will amply sustain the con tiguousends of the rai'ls,.and also provide means for locking the bolt-sandnuts which secure the fish plates .in place.

With the above and other objects in View, theinventimr consists in theconstruction, combination and arrangement of'parts, as will behereinafter more fully described, illustrated in the accompanyingdrawings, and pointed out in the claims hereunto appended.

in the accompanying drawings: Figure 1 is a side elevation of a railjoint embodying the present invention. Fig. a vertical cross sectionthrough the same. Fig. 3 is a detail perspective view of one of the fishPlttlTQS, looking toward the outer side. Fig. t is a perspective view ofone of the chairs. Fig. a similar view of the opposite chair.

ltei' erring to the drawings, 1 and :2 designate a pair of rail ends, 3fish plates ..a1'- ranged at opposite sides thereof, and 4 the boltswhich secure the fishplates to the rails. Each of the fish plates hasits central. portion thickened or. reinforced, as shown at. 5, and theend portions of the reinforce are cut-away or rab'beted, as shown at 6,so as to leave horizontal shoulders 7, against which bear the uppersurfaces of. oppositely arranged chairs'8, and 9, the chairs. thusforming a thorough support for the fish plates at opposite sides of therails, it being uiwlerstood that two of such fish plates are employed,one the counter-parhof the other. l lach of the fish platcstl isprovided at its opposite ends with holes and 11, and one of said holesshould be in the form of a slot extending lengthwise ot the fishplatefso as to inlmit of the-necessary expansion and obntraction of therails, due/to changes in the weather. While the fish plates are thecoiinter-part of each other, they are arranged reversely to each other,or in other 'words, end for end, so that the slot 1n the on the fishSpecification of Letters resent. Pat t 11, 1 Application filed .lanuary26, 1912. Serial Just above the slot of eachfish plate is an elongatedshoulder 13 which lies close to one side of the head of the adjacentbolt, so as to prevent said bolt from pf the bolt is provided with acollar having ratchet teeth 15 formed therein adapted to be engaged by apawl 16 pivotally mounted plate adjacent to the nut, as clearly shown,so that the pawl will click in engagement with the said ratchet teethand prevent the nut from working loose.

Two sets of chairs are used in connection with each pair of fish platesat each rail joint. One of the chairs 9 is formed integrally with thebase plate 17 which extends under the rail and is provided in its underside with a recess 18, and in its end with aslot 19 adapting it toreceive the other chair 8, en'ibodying a shank 20 which fits in theturning. The nut 14 slot 19, andoppositely extending flanges 21 whichfit into the recess 18, whereby the chair 8 is made separable from theother as the nut is tightened,,

chair. and at the same time held in proper relation to the fish plate,when the flanges 21 are engaged in the recess 18.

It will be understood that the fish plat-es fit snugly against the webof the rail between the head and bottom flange, and the reinforce 5extends downwardly and also rests in contact with the base of the rail.The shoulders 7 are supported directly upon the chairs 8 and 9, andthese chairs may be piked or otherwise secured to the supportng ties.

\Vhat is claimed is:

' 1. In a rail joint, the combination of two rail ends, fish plates atopposite sides thereof provided at their upper corners with overhangingchair engaging shoulders, and sets of chairs located at the ends of thefish plates and engaging under said shoulders, each set coin n'ising twooppositely arranged chairs, one of which embodies a base plate an openslot therein,- the other chair having a projecting shank fitting intosaid slot.
